Super Fusion! (いよいよ完成！超フュージョン！！, Iyoiyo Kansei! Sūpā Fyūjon!!; lit. "Perfected at Last! Super Fusion!!") is the four hundred eighty-second chapter of the Dragon Ball manga.
The cover of this chapter shows Gohan, Mr. Satan, Gotenks, Piccolo, and several Majin Buu duplicates. This cover art is also featured in Daizenshuu 1.
Goten and Trunks fuse as Super Saiyans, and form Gotenks. He wastes the whole thirty minutes flying around Earth, and the fusion splits right before they were about to face Majin Buu.
